The Year of the Zebra

When You Hear Hoofbeats, Think Horses—Not Zebras

In medical training, healthcare professionals are often taught to consider common diagnoses (“horses”) first, rather than rare conditions (“zebras”). While these “zebras” are uncommon on a global scale, their impact reaches far and wide, affecting countless lives around the world.

2023 marked the 40th anniversary of the Orphan Drug Act. In recognition of this, Elsevier introduced “The Year of the Zebra” initiative. Our mission: to bring rare diseases and their impacts to the forefront, educate both future and practicing clinicians, and connect patients, families, and researchers with reliable, open-access resources.

We continue to shine a spotlight on rare diseases through monthly Osmosis style videos and newsletters, each highlighting a different rare “zebra” condition, Zebra-specific podcast series and the “I am a Zebra/I know a Zebra” video series sharing personal stories from those affected by rare disease. The initiative continues to drive awareness of and support for rare diseases in the healthcare community and to educate and uplift the rare disease community.

The next time you hear hoofbeats, remember—sometimes, they belong not just to horses, but to extraordinary zebras.

Rare Disease Day

The first Rare Disease Day was celebrated on February 29th, 2008 - the rarest day given that it only occurs every Leap Year. Since then, Rare Disease Day has been celebrated on the last day of February. On this day the world comes together to show support for the 400+ million people inflicted by 7,000+ rare diseases globally and those who care for them! On Rare Disease Day in 2023, Osmosis from Elsevier launched our global Year of the Zebra initiative to drive more awareness of and support for rare diseases in the healthcare community. 

Importantly, that first Rare Disease Day back in 2008 marked the 25th anniversary of the Orphan Drug Act, which revolutionized the way treatments and cures are developed for rare diseases. Today, the Year of the Zebra is a renewed commitment to achieving an inclusive healthcare system, to educating as many people as possible, and to leveraging Osmosis’ far-reaching network of followers and subscribers to ultimately drive research, action, and improve patient outcomes. 

Moving forward, each month, we will continue to feature one new video highlighting a rare disease or “zebra” in our monthly Year of the Zebra newsletter. That video will also be featured on our YouTube channel.

Please help us to continue to spread the word about this worthy and important initiative in the year ahead.

I am a Zebra/I know a Zebra

As part of Elsevier's ongoing commitment to the Year of the Zebra initiative, we continue to add new videos to our I am a Zebra and I know a Zebra series, in which people from around the world tell us firsthand how a Zebra condition has impacted their life - either from having a Zebra condition (I am a Zebra) or knowing someone with a Zebra condition (I know a Zebra).
